EMMA F. JAY BULLENE, OF CHICAGO, ILLINOIS.

vENTlLATED CUSHION.

SPECIFICATION forming part of Letters Patent No. 442,099, dated December9, 1890. Application filed October 14, 1889.` Serial No, 327,036. (Nomodell) long axis of the strips B and B. I then To all whom it mayconcern.-

Beit known that I, EMMA F. JAY BULLENE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement inVentilated Cushions, of whichthe f ollowing is a specification.

My invention relates to ventilated cushions, in which a stuffed orupholstered cushion is secured upon the top of a frame-work resting on aset of springs made of fiat steel bent in a curve, the said cushion andspx-ing being inclosed in a cover or envelope secured to the lower pieceof the frame, and being perforated with a series of eyelets orventilators. y

The object of my invention is to provide a ventilated cushion that willbe highly elastic and that will renovate itself by the ventilationprovided in the use of the eyelets or ventilators. I attain this objectby means of the device shown in the annexed drawings, in which- Figure lis a section of the cushion made in the middle line. Fig. 2 is a planview of the cushion with the cover removed. Fig. 3 is a view of thecushion, showing the ventilators. Fig. 4 is a sectional and plan view ofthe button Il. Fig. 5 is a view of the button K and the end of a springF. Fig. (5 is a detail View of the springs G G.

Similar letters refer to similar parts throughout the several views.

I make a frame A and A', composed of strips of suitable material forholding thc springs G and F, the said strips being placed at rightangles, as B', and diagonally, as B. On the strips B and B at convenientpoints I secure a turn-button II,which has a flat-tened elongated head aand a shank @which is riveted at c to the strip B, and may be turned inthe socket in B to secure the springs G G, which said springs G G haveeach of them an elongated hole X cutin the center, through which passesthe head a of the button II. On the crosspieces B and the diagonalpieces B, at the ends, I secure Va fixed button K, a square shank g ofwhich perforates the strip B and B and the frame A and A and is providedwith a head h to secure it to the strips. Ihe upper part of the button Kis prolonged into a iiattened head, set at right angles with the make aseries of steel springs F and G, and in the case of the springs G7 Imake them in the form of a hoop, and at convenient points of the sidesof the hoop I make an elongated hole X to accommodate the head a of thebutton II. I Then make a second series of steel springs and bend them ina curved manner, and in the ends of each I make an elongated hole d anda square prolongation of the same e. The elongated hole d is made toconform to the shape of the head of the button K and the prolongation eto fit the shank g. On the lower element of the frame A, at convenientpoints, I place stop-posts P, designed to prevent the springs G and Ffrom collapsing too far.

On the t-op of the frame A and A,I make a pad C, which maybe of, hair orany other suitable material to form a cushion, and over th-is pad C, Imake a web D, which is a cover or envelope to the pad C and frame A andA,and at convenient points in the cover or web D,I make a series ofventilators E,which are made in the form of an eyelet and riveted to theweb D, the object of the ventilators being to allow of a currentof airpassing in and out of the body of the cushion by the compression andexpansion of the springs.

Having thus described the part-s of my invention,I nowprocecd to explainthe method of using the same.

I put the frame A and A together and adjust the springs G on thediagonal strips B', turning the button II to hold them in place. I thensecure the springs F by compressing them and slipping the ends over thebutton K, then turning the springs in a line with the strip B or B', asthe case may be, so that the elongated part e of the hole d will be inline with the shank g of the button and the spring beheld from turning.I then place the stopposts in position and secure the pad C, then placeover the whole the cover or web D, and secure the lower edges by tacks.

I am aware that spring-cushions have been in use prior to my invention,and I do not therefore lay claim to the broad principle ofspring-cushions; but

What I do claim, and desire to secure by Letters Patent, is-

I. In a ventilated cushion, a frame com- IOO posed of cross and diagonalstrips, consisting of a lower set of strips, stop-posts, a series ofbuttons having a ilattened head and square shank, and a central but-tonhaving a round shank, the said button being movable, combined with aseries of flat steel springs held in place by a series of buttons havingsquare Shanks, the said springs supporting the upper set of strips, allas and for the purpose substantially as set forth and described.

2. In a ventilated cushion, the combination of alower and upper framecomposed of strips, the said strips carrying a fixed button with anelongated head and having a square shank,

combined with a steel spring having a curved I5 form and having the endsperforated with holes, having,` an elongated portion to correspond withthe head of the said button, and la prolonged portion cut square tocorrespond with. the square shank of the said button, all zo
